But within 24 hours, drones (aka unmanned aerial vehicles) were blamed for impeding fire fighters’ efforts to contain a wildfire that jumped Interstate 15 in southern California, burning some 30 vehicles and sending some drivers running for their lives, according to CNN and others. The presence of five drones caused the grounding of fire-fighting aircraft for about 25 minutes, delaying emergency responders.

This was the third time that firefighters in San Bernardino county, California, were obstructed by drone activity, according to Slate.
